Answer:

The function is negative in the following intervals

A [-6, -4)

D (0.6)

Step-by-step explanation:

The function shown in the graph is negative for all values of x where y<0.

To answer this question, identify on the graph the pieces of the function that are on the negative axis. Then identify the values of x for which this occurs.

Observe the marked intervals in the attached image. The first goes from [-6, -4) and the second goes from (0, 6).

Therefore the correct option is:

A [-6, -4)

D (0.6)

Answer:

the number of sponges per package bought be 32.5

Step-by-step explanation:

Let us assume the number of sponges per package be x

So the number of packages he bought be x - 14

And, the overall he bought 51 sponges

the number of packages of sponges did roger buy is

x + x - 14 = 51

2x = 51 + 14

2x = 65

x = 32.5

So the number of sponges per package bought be 32.5

Answer:

$\frac{3}{2}$

Step-by-step explanation:

Given the expression:

$\frac{n+3}{2n-6} \div \frac{n+3}{3n-9}$

We are to find the quotient as shown:

$= \frac{n+3}{2n-6} \div \frac{n+3}{3n-9} \\\\= \frac{n+3}{2n-6} \times \frac{3n-9}{n+3} \\\\= \frac{n+3}{n+3} \times \frac{3n-9}{2n-6}\\\\= 1 \times \frac{3(n-3)}{2(n-3)}\\\\= 1 \times \frac{3}{2} \\\\= \frac{3}{2}$
